RIFT YANG This data model is defined according to [draft-przygienda-rift]. This model includes protocol configuration, state information, some notifications and RPC(TBD). Some features are added to enhance protocol.

RIFT configuration augment /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol: +--rw rift! +--rw node-info | +--rw systemid systemid | +--rw address? inet:ip-address | +--rw level-flag? enumeration | +--rw level-value? level-value | +--rw name? string | +--rw pod? uint16 | +--rw hal? level-value | +--rw ol? boolean {overload}? | +--rw ztp? boolean {ztp-mode}? | +--rw bfd? boolean {bfd}? | +--rw default-originate? boolean {default-route-originate}? | +--rw flood-reducing? boolean {flood-reducing}? | +--rw interfaces* [local-id] | | +--rw local-id uint32 | | +--rw name? if:interface-ref | | +--rw intf-type | | +--rw link-type? enumeration | +--rw community | | +--rw type? enumeration | | +--rw value? uint64 | | +--rw action? enumeration | +--rw policy-info {policy}? | …… The configuration includes node info, interface info, policy info. Base node configuration includes node systemid, address, node level, etc. Policies include community and policy-guide-information. Some features can be used to enhance protocol, such as BFD, flooding-reducing, overload bit and default-route-origination. etc.
